Beit known that l, CHARLES H. BimennNs'rmN, a citizen oi' the United States, re-

sidingr at Vinton, in the parish oi: Calc-asien and @tate or Louisiana, have invented certain new and .useful Improvements in Leakv' prooic Lower or Standing Valves, ot which the 'following is a full, clear, and exactdey scription thereof.

My invention relates rto the body oi a lower orl standing valve used in oil-well pumps and in other deep well pumps and one of the objects olf my invention is to provide a valve of this character which is adapted to be used with the presentstandard ball, seat and cage valve; and also with the standard `working barrel and the standard lworking barrel collar; it being un necessary to make any changes whatsoever either in the standard ball and cage 4valve, or in the standard working barrel collar.

Another important feature of' my invention resides in the provision ofa valve ot this/character which prevents any leakage of the oil or other liquid between the valve and the working barrel.A @ther objects of my invention are to produce a valve of this type whichis economical both 4in manufacture' andin use; which may `be easily and readily mounted in or removed from the standard working barrel and also one which operates with greater ease and with greatereiciencythan similar valves now known.

The present standard oil-well or other deep well pump includes a working barrel, having a collar mounted on the lower end thereof, and the interior of this collar is provided with a seat;A and engaging 4this seat is the lower or standing valve, which in standard practice comprises the body to which is attached at the top the usual ball, seat and cage valve, and which body is surrounded by a number of leather washers, the function of which is to prevent any leak age of the oil or other liquid between the valve and the working barrel. Obviously such a construction does not produce la leakproof connection between 'the lower valve and the working barrel. lt is my purpose to provide a lower valve which is notonly absolutely leak-proof, but also which 1s inexpensive to manufacture and install, as it necessitates no changes whatever 1n` the standard ball, seat and cage valve, the standard working barrel, or the standard working barrel collar. v f

' 7Vith the above and otherobjects in view my apparatus which accomplishes the above accompanying drawings, y in which Figure l is avertical sectional view .of the lower or standing valve; the ball, seat, and cage valve being in elevation.

'Figure 2 is'a side elevation of the tapery ing lead washer g. and

Figure 3 is a plan view thereof.

Numeral lvdesignates the standard 'working barrel collar or coupling,`and.wh1ch 1s Aprovided with the usual taperingseat 2. l

also show 'a portion of the working barrel 3 screw-threaded into the top of the working barrel collar, and the 'perforatedfpipe ,4f screw-threaded into .the bottom thereof. All of the kforegoing isthe standardfstructure in oil-well orlother ydeep well' pumps, and .any further description thereof is bef lieved to be'unnecessary.v f e The body of the standing valve consists of a tubular member 5, which may be screwthreaded at bothl ends,rand intermediate of the ends vand preferably formed integral vwith the bodyis-the shoulder. rEhe stand;

ard ball, seat, and cage valve 7" is adapted to be scr/e'wthreaded onto the upper end of the body member. y y l Arle'ad or othery softvmetal washer 8' is adaptedto be fitted over'the body member, under the shoulder 6. The interior `of the washer is cylindrical,v but Athe exterior thereof is tapering and is designed to be wedged down into. the standard tapering seat 2 of the working barrel collar 1.

A small coupling 9 is screw-threadedly engaged with the lower end of the tubular y .l will now proceed to descriloe one Jform of. l

4and, other objects, reference being had to the eisv i so

body member, the couplingv abutting the y bottom of the seat 2. It will now be yevident that by rotating the coupling 9, the body member with its shoulder 6, will be drawn downwardly; and the shoulder engaging the taperinglead washer will torce it with a wedging action into the space between the body member and the'seatV 2, thereby /forming an absolutely leak-proof joint between thelower or standing valve and the working barrel of the pump. The coupling 9 is shown of sufficient size for the attachment of a gas anchor should one be desirable.

The ease and rapidity with `which the valve is assembled will be apparent from the foregoing description. All that is necessary is to place the sott metal washer on the tubular body member carrying the ball, seat, and cage kvalve; the working barrel collar is then passed over the body member under the shoulder, and is screwed onto the working barrel. The coupling 9 is now screwed onto the lower end ot the body member whereby the shoulder forces the washer into the tapering space between the seat 2 and the body member, forming the desired leal'- proof joint between the working barrel and the standing or lower valve.

lt will also be apparent that I have produced a leak-proof lower valve, which necessitates no changes whatever in the standard ball, seat and cage valve, the standard working barrel collar, or the standard working barrel; thereby producing a lower valve which is economical both inmanufacture and use.

Although I have shown and described what l consider to be the best'torm ofconstruction of my imp-rovedlower or standing valve, it is evident that alterations or 'tapering seat provided insaid collar, a tubular body member, a tapering soft metal washer associated therewith, and means for ldrawing the body memberv and shoulder drawing the body member and washer downwardly whereby the latter is wedged' into thc space between the seat and the body member, said means engaging the under :tace ot the seat.

2. A `lower valve for deep well pumps,

including a working barrel collar, a tapering seat provided in said collar, a tubular body member, a tapering lead washer, a shoulder provided on the body member, and means for drawing said body and shoulder downwardly, whereby the washer is wedged into the space between the seat and the body member.

A lower valve for deep well pumps, in cluding a working barrel collar, a tapering vseat provided in said collar, a tubular lbody` member, a tapering lead washer,a shoulder provided on said body member, and a coupling threadedly engaging the body mere ber and abutting the bottom oit said seat, whereby the washer may be wedgedinto the space between the seat and the body member.

4C. A lower valve for deep well 'pumps,'in cluding a working barrel collar, a tapering seat provided in said collar, a tubular body member, a taperinglead washer, a shoulder provided on said body member, a coupling threadedly engaging the body member and abutting the bottom ot said seat, whereby the washer may be wedged into the space between the seat and the body member, said coupling being adapted 'for the attachment oit a gas anchor. K.

5. A valve of the character described including a standard working barrel collar, ak

standard tapering seat providedV in said collar, a tubular body member, a standard ball, seat and cage valve attached to the upper end of the body member, a tapering lead washer, a shoulder provided on said body member, .and a coupling threadedly engaging the lower end of the `body member and abutting the bottom of said seat, for

downwardly, whereby the lead washer is wedged into the space between the tapering seat and the body member.l
